Tex on wikipedia

you type	you get
<math>a^{c+2}</math> now the text is displayed as html	$a^{c+2}$
<math>a^{c+2}\,\!</math> but we can force to use png instead	$a^{c+2}\,\!$
but when formula is more complicated, it cant be shown as html <math>f(n) = \begin{cases} n/2, & \mbox{if }n\mbox{ is even} \\ 3n+1, & \mbox{if }n\mbox{ is odd} \end{cases}	$f(n)={\begin{cases}n/2,&{\mbox{if }}n{\mbox{ is even}}\\3n+1,&{\mbox{if }}n{\mbox{ is odd}}\end{cases}}$

list of all possible tex commands can be found here

• for example we can create boolean formulas, like shown below

you type	you get
p \lor \bar{q} \to p	$p\lor {\bar {q}}\to p$

• we can use different matrixes

you type	you get
<math>\begin{matrix} x & \cdots & y \\ \vdots & \ddots & \vdots \\ z & \cdots & v \end{matrix} </math>	${\begin{matrix}x&\cdots &y\\\vdots &\ddots &\vdots \\z&\cdots &v\end{matrix}}$
<math>\begin{vmatrix} x & \cdots & y \\ \vdots & \ddots & \vdots \\ z & \cdots & v \end{vmatrix}</math>	${\begin{vmatrix}x&\cdots &y\\\vdots &\ddots &\vdots \\z&\cdots &v\end{vmatrix}}$

• fractions:

you type	you get
<math>\frac{2}{c + \frac{2}{d + \frac{2}{4}}} = a</math>	${\frac {2}{c+{\frac {2}{d+{\frac {2}{4}}}}}}=a$
<math>\cfrac{2}{c + \cfrac{2}{d + \cfrac{2}{4}}} = a</math>	${\cfrac {2}{c+{\cfrac {2}{d+{\cfrac {2}{4}}}}}}=a$

• bracers:

you type	you get
<math> ( \frac{1}{2} )</math>	$({\frac {1}{2}})$
<math>\left ( \frac{1}{2} \right )</math>	$\left({\frac {1}{2}}\right)$

• over and underbracers:

you type	you get
<math>\overbrace{ 1+2+\cdots+100 }^{5050}</math>	$\overbrace {1+2+\cdots +100} ^{5050}$
<math>\underbrace{ a+b+\cdots+z }_{26}</math>	$\underbrace {a+b+\cdots +z} _{26}$
